I see the value in this.
But would probably just set my kitchen oven to “warm” at 170deg and place items in there.
I have the 3M N95 respirator for when I am in a close environment where there is a high risk.
For day stuff like if I walking down a sidewalk with some distance between me and other people, I am using N99 Base Camp dust mask breathe safe. I have a bunch of refill carbon filters for it. You can pull the filter out and wash it.
